It's set in a world where the animals control the planet and humans are the minority. Brandt said "Creatures" is a "big, fun, fantastic 'Jurassic Park'-type movie."

"Because of people's inability to quench their thirst for oil and consumption of resources, we basically ruin the planet, and the planet fights back," Brandt said. "And part of that is the quick evolution of many of the animals."

"Creatures" takes place in North America, "where people are literally living in forts, and the animals are running free," he added. "It's not like dogs and cats are killing people, it's that the strong have survived. Lions and bears and animals like that have all evolved, and they're slowly eating away at the human population."

Brandt and Haas are also the writing force behind such films as "2 Fast 2 Furious" and "3:10 to Yuma."

From a scientific stand-point it will be interesting how they will accomplish this movie. Humans are versitile and are able to change as their surroundings change. Animals are not so easily able to change habits, it would take decades for animals to change behaviors and possibly millions of years to evolve into super predators. I guess we'll just have to wait and see.
